An international team of researchers have found in a meta-analysis that vitamin D supplementation may alleviate depressive symptoms in adults with depression.
The research has been published in the journal Critical Reviews in Food Science and Nutrition.
Depressive symptoms cause a significant disease burden worldwide. The therapeutic efficacy of current antidepressants is often insufficient, which is why further ways to alleviate the symptoms of depression have been sought, for example, from nutritional research.
Vitamin D is believed to regulate central nervous system functions the disturbances of which have been associated with depression. In addition, cross-sectional studies have observed an association between depressive symptoms and vitamin D deficiency. However, previous meta-analyses on the effects of vitamin D supplementation on depression have been inconclusive. In a meta-analysis, results from several different studies are combined and analysed statistically.
The new meta-analysis on the association of vitamin D supplementation with depression is the largest one published so far, including results from 41 studies from around the world. These studies have investigated the efficacy of vitamin D in alleviating depressive symptoms in adults by randomised placebo-controlled trials in different populations.
The studies included those carried out in patients with depression, in the general population, and in people with various physical conditions. The results of the meta-analysis show that vitamin D supplementation is more effective than a placebo in alleviating depressive symptoms in people with depression. There were major differences in the vitamin D doses used, but typically the vitamin D supplement was 50–100 micrograms per day.
"Despite the broad scope of this meta-analysis, the certainty of evidence remains low due to the heterogeneity of the populations studied and the due to the risk of bias associated with a large number of studies," Doctoral Researcher and lead author Tuomas Mikola of the Institute of Clinical Medicine at the University of Eastern Finland says. The meta-analysis is part of Mikola's PhD thesis.
